This invention has to do with binders such as are commonly employed inlooms for the purpose of holding the shuttle after each pick.

The problem of providing a binder that will properly receptively engageand hold a shuttle after each pick is extremely important, particularlywhen the loom is of the automatic type which involves the automaticreplacement of bobbins in the shuttle. In the first place, properreceptive engagement of the shuttle with the binder insures of theshuttle assuming a straight position. This is advantageous both from theaspect of providing even wear on the shuttle, and in the making of thesubsequent pick. Furthermore unless the shuttle is properly positionedand firmly maintained in that position there is a strong tendency forthe automatic replacement of the bobbins to be attended by such resultsas broken shuttles, bobbins and other damaged parts.

With the foregoing conditions in mind this invention has in view, as itsforemost objective, the provision of an improved and novel binder forshuttles which is characterized as providing for highly improvedreceptive engagement of the shuttle with the binder, as well as animproved and novel arrangement for firmly holding the shuttle inposition.

In carrying out this objective the invention has in view, as animportant feature, the replacement of the old wood and leather typebinder with an all metal binder having a polished surface that engagesthe shuttle.

A further object of the invention is the provision of an improved binderof the character above noted together with means for mounting the sameon the shuttle box of the loom to provide for an improved floatingmotion on the part of the binder. Particular objects and advantages ofthe invention are associated with the provision of this means forproviding the improved floating motion.

In the looms of present day construction the general practice is toprovide a pressure finger adjacent the innermost side of the shuttle boxfor engagement with the binder to apply pressure thereto, which urgesthe same against the shuttle at a zone more closely adjacent to thepicker. With this arrangement there is a tendency for the outermost noseof the shuttle to become displaced and assume a position that oftencauses disastrous results as the bobbins are changed.

Accordingly, this invention has in View, as another highly importantobject, the provision of 1938, Serial No. 226,094

a binder of the character above described which has associated therewitha so-called auxiliary binder which is effective to engage the shuttleadjacent its outer nose, under pressure, to firmly position the shuttle.

Another more detailed object of the invention is the provision of anauxiliary binder of the character above noted which is so arranged withrespect to the main binder that the application of pressure on the mainbinder in the usual manner by the conventional pressure finger isrendered eifective to cause application of pressure by the auxiliarybinder.

Various other more detailed objects and advantages of the invention willin part become apparent and in part be hereinafter stated, as thedescription of the invention proceeds.

The invention, therefore, comprises a novel binder which includes meansfor mounting the same on a shuttle box to provide and improved floatingaction, and an auxiliary binder associated therewith for applyingpressure on the shuttle adjacent to its outer nose.

For a full and more complete understanding of the invention referencemay be had to the following description and accompanying drawing,wherein:

Figure 1 is a plan view of a shuttle box having the improved binder ofthis invention associated therewith,

Figure 2 is a side view of the structure shown in Figure l, and

Figure 3 is a diagrammatic view bringing out the relationship of theparts when the shuttle is out of the box.

Referring now to the drawing, wherein like reference characters denotecorresponding parts, the end of a lay is designated IE) and is shown ashaving an opening at H (dotted lines, Figure 1) through which usedbobbins pass from the shuttle i during the automatic replacementthereof. The lay In constitutes, in effect, the bottom of the shuttlebox. At one side the lay l0 carries a box back in the form of a plate 52which preferably is of metal having an inner polished surface with whichthe shuttle engages. At one end the lay i H and box back 42 carry a boxend identified at I3, and this box end houses the picker in the usualmanner.

Carried by the lay it? and spaced the required distance from the box end13 is a bracket referred to in its entirety by the reference characterB. This bracket B includes a bottom plate l4 that extends outwardly fromthe lay IE1 and from which upstands an outer strut l5, and an inner walll6 that is covered with leather, as shown at IT, to constitute the samea hunter.

Connecting the strut l5 and wall 16 at the top is a cover plate 18. Apivot pin l9 extends between the bottom plate l4 and cover plate 18, andmounted on this pivot pin I9 is the auxiliary binder referred to in itsentirety by the reference character 20. This auxiliary binder 20 takesthe form of a bell crank having one arm at 2i and another arm 22 that isof a bent formation and having a rounded extremity at 23 for engagementwith a shuttle. The bottom lower edge of the arm 22 is cut away toprovide a recess 9 for a purpose to be hereinafter pointed out.

The usual safety finger which is included in looms of this type isreferred to generally at 24, and the arm 2i of the auxiliary binder 20is adapted to engage therewith when the shuttle is seated in the box inthe usual manner.

The improved binder of this invention is referred to in its entirety bythe reference character 20. In accordance with this invention the binderpreferably made from a single bar of metal and is formed with the mainbody portion 2 that carries, at the end adjacent to the box end it, anend flange 2? that is formed with a slot 28. The slot 28 terminates inan end wall 28 formed with a threaded opening that carries a set screw Anut 35 is in turn carried by this set screw 36. The inner end of thisset screw 30 projects into the slot 28 for a purpose to be hereinafterpointed out.

A bracket 32 is secured to the box end l3, as by the screw and nut shownat 33 and this bracket 32 has a turnedout flange 2 3 from which projectsa lug 35 that extends through the slot 28. A cotter pin shown at 3%serves to maintain the assembled relationship of the binder end 27 andthe bracket 32. At the same time the floating motion on the part of thebinder is provided for by the slot 28 and lug 35, and the amount ofmotion permitted may be varied by adjusting the set screw 39.

At the front end the binder 25 is formed with a so-called offset arm 3!which is integrally connected with the main body portion 26 by theinclined part 38 that is formed with a. slot 39 through which a feeler(not illustrated) is adapted to pass. The arm 31 is reduced in width, ascompared to the main body part 26, and passes through the recess 9 inthe arm 22 of the auxiliary binder 28.

At this point it is well to note that the binder will be made from ametal adapted to present a polished inner surface, the inner surfaces ofthe parts 26 and 38 being polished, as it is with the inner surfaces ofthese parts that the shuttle is adapted to engage. It is also importantto note that the lower edge of the binder 25 is maintained in upraisedspaced relationship from the lay ii as is clearly depicted in Figure 2.VJhile the spacing may be varied within reasonable limits the inventioncontemplates an arrangement wherein the spacing is substantially onequarter of an inch.

It is important to note that the offset arm 37 of the binder 25 extendsbetween the strut l 5 and wall N3 of the bracket B, and normally engagesthe arm 2! of the auxiliary binder 20.

The usual pressure finger included in the looms is referred to generallyas 46, and, as shown inv the drawing, this pressure finger engages themain body part 26 of the binder 25 at a point closely adjacent the boxend IS.

A shuttle is referred to generally by the reference character S and maybe of the usual type now meeting with use in automatic looms. Theoperation and mode of functioning of the improved binder of thisinvention may be described by noting that with the shuttle S out of thebox, the binder 25 and auxiliary binder 20 will assume the positionsdepicted in Figure 3. Under this condition pressure is not applied bythe pressure finger All to the binder 25, nor is the arm 2i inengagement with the safety finger 24.

With the shuttle moving into the box end the sides of the shuttle engagethe polished surfaces of the box back l2 and binder 25, and with theshuttle seated in the position shown in Figure 1, pressure is applied bythe finger 40 to the main. body part 25 of the binder 25. This pressurecauses the inner surface of the main flat body part 26 to align with thecorresponding flat surface of the shuttle S, thus causing an outwardmovement on the part of the arm 31, and the engagement of the latterwith the arm 2i of the auxiliary binder iii causes this arm 2i to moveoutwardly to engage the safety finger 24 and continue the operation ofthe loom in the usual manner.

At the same time the arm 22 of the auxiliary binder is moved inwardly sothat its rounded end 23 firmly engages the shuttle adjacent its innernose. Thus the shuttle is firmly held at two spaced points, one adjacenteach nose. The position of the various parts when the shuttle is so heldis shown in full lines in Figure 1.

The above described binder presents a distinct advantage over the usualwood and leather type binders that heretofore have met with widespreaduse in this art in that the metal will wear many times longer than willthe leather which has heretofore been employed on the inner sur facethat engages the shuttle. Another distinct advantage of the metallicbinder above described is that the frictional resistance encountered ateach side of the shuttle is substantially the same, as the resistance oneach side is caused by engagement with metallic surfaces. Thus when theshuttle is received in the box it will have a tendency to assume astraighter position than is the case when the old wood and leatherbinders are employed.

The binder of this invention presents the further advantage ofprolonging the life of the picker, as there is less friction of theshuttle as caused by the binder which must be overcome by the picker inthrowing the shuttle on its next shot.

Another highly important advantage of the metallic binder of thisinvention is that it may be bent to any required shape so that it may bepeculiarly adapted to use with any particular type of shuttle.

The slot bearing providing for the connection of the flanged end 27 toprovide the floating action presents a distinct advantage over now knownconnections for providing this floating action in that the slot 28 andlug 35 have interengaging bearing surfaces of appreciable length, whichserve to aid in maintaining the binder in proper position, particularlyin holding the face of the binder straight at all times. Thus when theshuttle engages the binder the face of the binder is substantiallyparallel with the side wall of the shuttle, and no force is required toalign these surfaces.

Furthermore, by providing the adjustable set screw 30, the amount offloating action on the part of the binder may be accurately controlledand adjustment made to adapt the floating action to any particular sizeshuttle which is being used.

With the shuttle held in position by the main body portion of the binder25 at one end, and the arm 2i of the auxiliary binder Ed at the other,change of bobbins may be automatically carried out without danger ofdamaging the shuttles, bobbins or yarn.

The use of a metallic binder of the character above described isparticularly desirable from the viewpoint that the collection of dirtand grease, which is inherently present with the wood and lea 191binders, is greatly diminished, if not substantially eliminated.

With the lower edge of the binder 25 spaced above the lay 50 greaterfreedom on the part of the thread carried by the shuttle is providedfor, and this is particularly true at the time of changing bobbins.

Another advantage afforded by the double grip that is provided for bythe binder 25 and auxiliary binder 29 is that the shuttle is gripped atboth ends. Thus the wear on the shuttle is more even and the tendency ofthe shuttle to wear down more at the eye end than at the other issubstantially eliminated.

The metallic binder of this invention is adapted to be substituted forbinders or" the Wood and leather type which are now meeting with use onautomatic looms, and when substituted therefor have been found toincrease the efficiency of production to a marked extent.
